“I was Jacek's mentor for a Google Summer of Code 2008 project. Jacek submitted a proposal to develop article tags for Joomla, an open course content management system. His proposal was one of the few selected among various submitted by college students around the world. Jacek was an excellent person to work with, who came to the project with a fully equipped skill set to complete a web CMS project written primarily for the LAMP platform. He required very little supervision to complete the project, but was very communicative through out the process and kept me informed of the progress. I wish Jacek the very best in his future endeavors.”Paul Ambrose - Department Chair at University of Wisconsin - Whitewater
